Abstract

Un dispositivo dosatore comprendente: un tubo di adduzione per la sostanza da dosare, chiuso alla sua estremità di erogazione e presentante presso tale estremità due aperture laterali di erogazione, una di grande sezione e l'altra, più vicina all'estremità di erogazione, di piccola sezione; un manicotto montato sul tubo di adduzione, scorrevole sostanzialmente a tenuta su di esso e terminante, verso l'estremità di erogazione del tubo, con un bordo affilato; un mezzo soffiante, montato sul manicotto e formante un ugello in corrispondenza delle aperture di erogazione del tubo di adduzione, questo mezzo soffiante presentando nel suo interno una camera, comunicante con l'ugello e connessa ad una sorgente di aria compressa; e mezzi per spostare il manicotto lungo il tubo di adduzione fra una posizione di erogazione, in cui il manicotto lascia scoperte entrambe le aperture di erogazione del tubo di adduzione, ed una posizione di intercettazione, nella quale il manicotto occlude entrambe le aperture di erogazione del tubo di adduzione, attraverso una posizione intermedia nella quale il manicotto copre l'apertura di erogazione di grande sezione ma lascia scoperte l'apertura di erogazione di piccola sezione.A metering device comprising: an adduction tube for the substance to be dosed, closed at its dispensing end and having at its end two lateral dispensing openings, one of large section and the other, closer to the dispensing end, of small section; a sleeve mounted on the adduction tube, sliding substantially tightly on it and ending, towards the delivery end of the tube, with a sharp edge; a blowing means, mounted on the sleeve and forming a nozzle in correspondence with the delivery openings of the adduction tube, this blowing means presenting inside a chamber, communicating with the nozzle and connected to a source of compressed air; and means for moving the sleeve along the adduction tube between a delivery position, in which the sleeve leaves both delivery openings of the adduction tube uncovered, and an interception position, in which the sleeve occludes both delivery apertures of the adduction tube, through an intermediate position in which the sleeve covers the large section delivery opening but leaves the small section delivery opening uncovered.
